摘要：

The maximum entropy principle formalism is applied in order to solve time-dependent N-level systems. The formalism, related to a quasi-Lie algebra, allows us to find not only the dynamical equations of the relevant operators for any temporal dependence of the interaction between levels, but also to diagonalize the associated off-equilibrium (temperature dependent) density matrix. A set of generalized Bloch equations, in terms of the relevant operators, is given. The time-dependent two-level case is analyzed as a particular example.
